The mold carrier 25 is suspended from these hearings by the trunnions 26 and 27. Trunnion 27 is extended sufliciently beyond the bearing 24 to receive the half-gear 1 28, which is rigidly secured thereto. Adjacent to and parallel with the trunnion 27 is the shaft 29, which is supported by the bracket 30 made integral with'the arm 19. Mounted onthis shaft is the'hand wheel 31 and the pinion 32, which is capable of meshing engagement with the half-gear 28. Normally it is held out of such engagement by the coil spring 33. By forcing same into mesh with the gear 28 and giving it a full turn by the hand wheel 31, the gear is given a half turn and the mold carrier is inverted from normal to position shown in dotted lines in Figs. 3 and 4:.

A pattern 34:, of any desired form, from which a mold is to be made is securely fastened to the mold carrier 25, as shown in dotted lines in Figs. 2 and 4. The flask 35 is placed around the pattern and filled with molding sand in the usual manner. Compressed air is then admitted into the lower end of cylinder 2 and the ram 4 moves up to its uppermost position in the cylinder, bring-' ing the jarrin plate 8 in contact With the underside of t e mold carrier, 25, lifting it slightly out of the bearings 24.

.With air at a suflicient pressure to unyieldingly hold ram 2 in its uppermost position and with jarrin plate8 in contact with mold carrier 25, air 1s admitted into valve 9 causing the reciprocation of ram/7 as above explained, and the free raising and falling of the mold carrier in the bearings 24.

When'the mold has been sufficiently jarred to properly ram the sand aboutthe pattern, the air is released from cylinder ,2 permitting ram 4 with its jarring plate to drop away from the mold carrier 25, leaving same suspended'inthe bearings 24. It is to be understood that the admission of air into cylinder 2 is in no manner to be connected with the jarring action of the device other than to form a solid unyielding'anvil to re ceivethe force of the falling mold during the act ofbeing jarred or jolted. The area of the iston in conjunction with the pressure 0 the airemployed determines the maximum weight of the mold, the falling force of which is to be unyieldingly resisted. If air of suflicient pressure to unyieldingly resist the falling force of an excessively heavy mold is not available, the device shown'in Figs. 5, 6 and 7 may be employed. This consists of the arms *36 hin ed at one end to opposite sidesof the cy-lin er 15 and provided at the other end with the semi-circulan-jaw's-B'? which, when closed, completely-envelop the ram 4: under the flange a end rest upon the upper end of the cylinlow pressure air for-raising the jarring plate and maintaining same in operative position}. After the arring plate has been lowered and the mold is suspended from the bearings 24 as above indicated, the pinion 32 is caused to engage the half gear 28 and given a full turn by the hand wheel 31 inverting the mold carrier 25, and the flask which has been clamped thereto, as shown in dotted lines in Fig. 3. For the convenience of the operator, the entire machine is located in a pit having a floor line as indicated at 39. A small four Wheeled truck 40 may be provided and arranged to 0 rate on the track 41 terminatin at the e ge of the pit with its upper sur ace in the plane of the upper face of the jarring plate 8 and in alinement with grooves or channels not shown out in the face of the plate for the accommodation of the truckwheels, so that thetruck can I This is accomplished by admitting1 air into the lower end of cylinder 15, w ich will cause the ram 17 and yoke 19 together with the mold carrier 25 to slowly rise to the position as shown in dotted lines in Fig. 4, carrying the pattern 34, which is secured to the mold carrier, with it.

Durin the act of withdrawing the pattern, a vibrator 43 of usual construction, and which is secured to the mold carrier, is set in action, rapping the pattern aiding in its withdrawal by lessening the probable tearing down of the sand mold. The truck with the finished mold is then pushed off the machine on to the track 41 and the machine prepared for another mold.
